' Patented Sept. 9, 1930 PATENT OFFICE GEORGE w. STEDWELL, or naooxmm. NEW YORK LIQUID-DISPENSING APPARATUS Application filed June 16, 1930. Serial No. 461,422.

This invention relates particularly to apparatus of the type in which gasoline or other liquid is delivered through a flexible hose nozzle valve 17 at the discharge end of the under control of a nozzle valve. The objects of. the invention are to provide simple, practical and efficient mechanism for throwing a switch, or operatinga valve or other flow governing mechanism from the nozzle end of the hose.

One of the important features of the invention is the provision of means by which pulling on the hose is madeeiiective to operate the desired control mechanism.

.Other novel features of the invention will appear as the specification proceeds.

The drawing accompanying and forming part of the specification illustrates several different forms the invention may take, but it should be understood that the structure may otherwise vary without departure from the true, spirit and broad scope of'the invention.

. Fig. 1 is a general side view showing the invention incorporated in a gasoline dispensing pump or stand. Figs. 2 and 3 are broken details of the control means shown in Fig. 1; Figs. 4 and 5 are broken details illustrating other embodiments of the invention.

The present invention is a continuation in 1 part of applications 323,411 filed Dec. 3, 1928,

. and 324,761 filed December 8, 1928, and issued asPatents'1,713,102 of May, 14, 1929, and 1,717,274 of June 11, 1929, respectively.

In the first illustrated form of the invenand 3, the control is effected by means of the hose 7 through the medium .of an extensible or telescopic section pro vided at the upper end of the hose and shown as a sylphon 8 and enabling in effect a stretching of the hose,

medium of a link 9 operates a bell crank lever '10 connected to a valve 11 controlling flow through the supply pipe 12 and a switch 13 I governing operation of the pump 14. The

* wiring from the switch'to the pump motor is indicated only'in a general way at 15 in Fig.

.1 and it should be understood that when switch is closed by pulling on the hose, the

pump motor will be operated to impel a flow which through the.

of liquid through the supply pipe 12, meter The amount of liquid de- 16 andhose 7. livered may be accurately determined by a hose and the pump may be started and stopped by pulling or releasing the pull on the hose, a return spring such as indicated at 18 being provided to turn of! the switch and the valve and to retract the hose when pull on. the same is released. This return spring is made heavy enough to accomplish this purpose and it is shown as directly connected to one arm of the bell crank lever 10. To facilitate the extension and contraction of the hose joint and prevent wear on the sylphon, the hose is shown as having a collar 19 at its upper end slidingly fittingover a" neck 20 on the elbow or goose neck 21 at the upper end of the hose line. Y

' In the second embodiment illustrated, the switch and valve are operated by a straight lever 22 connected by a link 23 with a band 24 encircling the suspended portion of the hose below the goose neck. A return spring 25 is provided in this instance and in both the case last described and in the first form illustrated, suitable stops 26 are indicated for limiting the switch throwing and valve operating movements.

In the, Fig. 5 form of construction, the upper end portion of the hose is equipped witha swivel or swing joint 27 and the swinging portion below this is connected by a link 28 with a lever 29 operating a supply valve 30 in the flow line and engaging the operating lever 31 of the switch 32, which controls the pump motor.

' In all forms of the invention, it will be observed that the flow operation may be governed by simply pulling on the hose to start the flow and by releasing pull on the hose to stop the flow. The natural effect of the hose to swing straight down. from the goose-neck at the top will have a tendency to restore the parts in Figs. 4 and 5, but this shutting 0E operation may be made certain by the suitable return springs 25 and 33. The parts may be arranged, sothat pull on the swinging portion of the hose in any direction will be efiective to throw-the switch or operatethe left or if he be at the valve, or both, so that the attendant may conveniently actuate the control no matter in what position he may be standing or no matter what position he may be in regard to the pump stand. In constructions like those shown in Figs. 4 and 5, it will be evident, the same control may be effected by a push action on the hose toward the left in these views instead of a straight pull toward the left, so thatthe attendant may accomplish the same control efi'ects either by pulling toward the right of the stand by pushing back on the hose, so as to effect the deflection on the hose as indicated in the dotted lines in Fig. 4. It will be understood.

therefore that the invention comprehends the deflection or shifting of the hose adjacent its supported end to effect mechanical actuation of the flow control mechanism, whether the latter be a switch or some other formof By this invention, the attendant at a pump stand is enabled to deliver continuously any desired volumes of liquid by simply operating the nozzle valve to start or to stop the flow and by using the hose in effect as a mechanical handle for throwing the switch or other control to start and stop the pump motor or the like, the meter at the pump stand at all times showing the amounts delivered in this way. The invention also involves a safety feature in that in the forms illustrated, the pum shut 011' as soon as t e actuating pull on the hose is released. Inattention or carelessness on the part of the operator therefore results in the flow being shut off. .The terms employed'herein areused in a descriptive rather than in a limiting sense, it being understood that equivalents may be employed as for instance, in place of the return springs 18, 25 and 33, counter-balance weights, pressure actuated means or the like, may used.

What is claimed is: 1. A liquid metering and delivery system comprisin a liquid delivery line terminating in a flexi 1e hose, suspended for pulling movement and having a manually operable nozzle valve by which discharge of liquid from the hose may be accurately determined, an electric pump for supplying'liquid under pressure through said delivery line and hose, a meter in the delivery line for showing the amounts of liquid delivered by the hose under control of said nozzle valve, a switch for starting and stopping the electric pump and flexible mechanical connections from said suspended pull portion of the hose to said switch for operating the latter to start and stop the pump by pulling movements on the hose, and

motor is automatically hose be left free of pressure after each delivery.

2. A liquid metering and delivery system comprising a liquid delivery line terminating in a flexible hose, suspended for pulling movement and having a manually operable nozzle valve by which discharge of liquid from the hose may be accurately determined,

an electric pump for supplying liquid under der control of said nozzle valve, a switch for starting and stopping the electric pump and flexible mechanical connections rom said suspended pull portion of the hose to said switch for operating the latter to start andstop the pump by pulling movements on the hose, and whereby various desired of liquid may be measured and dellvered b control exercised at the nozzle end of the hose and the hose be drained by operation of the nozzle valve after shutting off the pump and the hose be left free of pressure after each delivery and valve means in said system connected to be actuated by said hose pull connections.

In testimony whereof I affix my signature.

GEORGE W. STEDWELL.
